One of the most important features in the 7th National Curriculum of English is the introduction of the middle school multi-purpose English classes. Despite the importance of the classes, there doesn't seem to be enough studies of developing learning materials for them. The purpose of the current study is, therefore, to develop English learning materials for the multi-purpose English classes based on the Task-Based Learning framework. To do so, various tasks were collected and adapted for the classes, and different teaching techniques suitable for the tasks were designed. It is hoped that this research will help teachers prepare for teaching materials for the classes, and students recognize their interests in English and to improve their English abilities.

The effects of surface roughness on a turbulent boundary layer (TBL) were investigated using particle image velocimetry (PIV). The roughness elements used were periodically arranged two-dimensional spanwise rods, and the roughness height was ${\kappa}/{\delta}$. Introduction of the roughness elements increased the wake strength and the turbulent stress not only in the roughness sublayer but also in the outer layer. This indicates the existence of interaction between inner and outer layers for 2D rod-roughened wall. Roughness effects on a turbulence structure near the wall were obtained by PIV measurements. Iso-contours of mean velocities and Reynolds stresses in the roughness sublayer showed a very good agreement with previous DNS results.

The oscillatory excitation with a Strouhal number of 2.65 ncar the stagnation zone of hemispherical nose model was employed to control the laminar separation bubble and the transition to turbulence. The effects of oscillatory excitation upon the separation bubble and the transition were addressed in terms of kurtosis/skewness and time-frequency analyses. The measured noise spectrum of radiated sound from the turbulent boundary layer on the axi-symmetric infinite cylinder is compared with that by Sevik's wave-number white approximations. The noise sources in TBL on axi-symmetric cylinder and the caling of their far-field sound are also discussed.

Some numerical investigations are presented concerning the response of a given plate under turbulence driven excitations. Three different input loads are simulated according to the wall pressure distributions derived from the models proposed by Corcos, Efimtsov and Chase, respectively. Modal solutions (finite element based) are used for building the modal stochastic responses in the sub-critical aerodynamic frequency range. The parametric investigations concern two different values of the structural damping and three values of the boundary layer thickness. A final comparison with available experimental data is also discussed. The results demonstrate that the selection of the adequate TBL input model is still the most critical step in order to get a good prediction.

Previous studies have demonstrated that the three dimensions of Triple Bottom Line (TBL : economic, social, and environmental responsibility) indirectly affect product/corporate evaluation through reciprocity perception and trust (expertize-based trust and benevolence-based trust). Different from the past studies, this study investigates on the indirect effects as well as the direct effects of the three dimensions on product/corporate evaluation. The empirical results can be summarized as follows. First, reciprocity perception affects benevolence-based trust but it does not expertize-based trust. Second, the effect of economic dimension on product/corporate evaluation is not affected by reciprocity perception and benevolence-based trust, however, the effects of social dimension and environmental dimension on product/corporate evaluation are affected by reciprocity perception and benevolence-based trust.

본 연구는 TBL에서 학생을 보다 효율적으로 평가하기 위해 학생평가방법에 따른 평가점수 간 관계를 비교하고 그 관대함 정도를 분석하였다. 치위생학과 학생의 구강보건교육학 및 구강보건교육학 실습 교과목에서 학생평가방법에 따른 평가점수 간 관계를 살펴본 결과 지필시험과 팀별평가만 유의미한 중간 정도의 정적 상관관계가 나타났고, 그 외의 관계는 모두 유의하지 않았다. 학생평가방법에 따른 평가점수 간 관대함 정도는 팀원평가, 지필시험, 팀별평가 순으로 관대한 것으로 나타났다.

In a very competitive construction business environment there is a need to measure and manage business performance across a wider spectrum of business success criteria. The Balanced Scorecard (BSC) and Triple Bottom Line (TBL) reporting concepts are emerging as champions in the race for sustainable business success. The construction business organisations are often judged based on their financial performance as well as wider performance. This paper aims at developing a universally accepted tool for assessing contractors' wider business performance in the construction industry. A prototype of web-based business performance measurement system has been developed to help contractors assess their own performance aimed at uplifting their performance. The consultants/clients can also use the tool to measure contractors' performance in a value-based contractor selection. The system was developed based on the research conducted among 63 senior construction professionals and therefore further research with the participation of a large number of managers across different countries and also an upgrade of the system will be required.

본 연구는 팀기반학습을 활용한 교과목을 수강한 간호대학생 56명을 대상으로 동료평가와 학업성취도와의 관계에서 수업몰입의 매개효과를 검정하였다. 매개효과 분석은 PROCESS macro Program의 model 4를 부트스트래핑(bootstrapping)을 이용하여 검정하였다. 분석 결과는 첫째, 동료평가, 수업몰입과 학업성취도 간에 유의한 정적 상관이 있는 것으로 나타났다. 둘째, 수업몰입은 동료평가가 학업성취도에 미치는 영향을 부분매개 하는 것으로 확인되었다. 동료평가가 간호대학생을 위한 TBL 과정에서 수업몰입과 팀워크를 촉진하고 궁극적으로 학업성취도를 향상시키는 효과적인 도구가 될 수 있음을 시사하며, 교수자가 학생의 학습성과를 개선할 수 있는 보다 효과적인 교육 전략 및 개입을 개발하는 데 도움이 될 수 있다.

The purpose of this study was to examine the levels of sustainability of marine sport events by types of events and thus to provide fundamental information that helps developing sustainable marine sport events. In order to accomplish such the purpose, this study employed survey methodology with a total of 285 visitors to marine sport events. Questionnaires were developed based on Tripple Bottom Line theory suggested by previous research and validated throughout a panel of experts to check out content validity. Data collected were analyzed using descriptive statistics and ANOVA with Scheffe post hoc tests. Accordingly following findings were derived from current study. First, among 12 positive sustainability variables, marine space improvement had the highest mean score(M=3.82) but creation of jobs had the lowest mean score(M=3.46). Among 11 negative sustainability variables, traffic jab had the highest mean score(M=3.16) but conflict between participants and residents had the lowest mean score(M=2.73). Second, a festival typed marine sport event had the significantly high mean scores in all positive sustainability index including economic sustainability(M=3.79), social sustainability(M=3.84) and environmental sustainability(M=3.80). Third, a business typed marine sport event had the relatively higher mean scores in all negative sustainability index including economic sustainability(M=3.22), social sustainability(M=3.26) and environmental sustainability(M=3.25). In conclusion, these findings suggest that marine sport event organizers concentrate on marine sport event with more sustainability potentials.

The purpose of this study was to analyze differences in learning ability, team satisfaction, and learning preference depending on teaming method and the key sub-variables involved in communication ability,, problem solving ability, self-directed learning ability changes before and after team-based learning, and then to apply a team-based learning method to nursing curriculum. From October to December, 2016, 96 first-year nursing students and 108 second-year nursing students of the K University in G city took TBL classes and their observation values before and after TBL classes was analysed with SPSS and Medcalc programs. The results of this study showed that team-based learning was effective in improving communication ability, problem solving ability, self-directed learning ability, and preference to team-based learning was high in teams composed of academic achievement. It is expected that team-based learning can be settled in the curriculum by emphasizing that students learn problem-solving and communication abilities through self-learning and team dynamics before the class, and that it also is a learning method that improves professionalism and individual development. More researches are needed to focus on various factors such as the methodological composition of team-based learning and the preferences of individual student characteristics and learning methods.
